I believe it autoloads the latest episode of Wetten, Dass?.Yeah, I'm just seeing them on eBay from Germany. Do you know if the Kiezle is in English?
(At least I didn't say David Hasselhoff.)
There's an unboxing video of the Kienzle:
The Porsche people paint that shiny knob black.
May I suggest a few more options:
1. Pioneer makes some very low-key head units.
2. Marine radios, like from Clarion, often have a simple look that fits well. Also radios for trucks. Both are sold on Amazon. (And no, I don't know why you'd specifically want a simpler look in a marine or truck radio, but that's the market demand. Maybe because you have a lot of different operators who may not be familiar with a unit's intricacies?)
3. Blaupunkt -- now a Shenzhen shop, unrelated to the old Blaupunkt -- makes some nice-looking head units that are absolute crap as far as sound and build quality. Oh wait, just like the old Blaupunkt. Anyway, that's an option. And at least the new Blaupunkt, unlike the old Blaupunkt, is very attractively priced.
